peex_3a_n.jpg: Picture of the chest centered on the funnel. The visible funnel is caused by a depression of the lower sternal half at the deepest point; in additon, several adjacent pairs of rib cartilage take part of the funnel. Moreover, the rib cartilages of the left side follow a steeper course than those of the ride side. Notice the asymmetrical site of the mammilla in relation to the midline.
peex_3b_n.jpg: Operative findings after detachment of the chest wall muscles from the rib cartilages. On a view from the left side of the patient, the less steeply ascending rib cartilages of the right side are recognizable next to the right wound edge in contrast to the steeply ascending blurred left-sided cartilages.
